SPRINKLER HEAD SHUTOFF DEVICE I Joseph D. Tessier, Worcester, Mass. Application August 11, 1939, Serial No. 289,646

" ,7 Claims. (01.169-1) The objects of this invention include the pro- When the conventional sprinkler head 48 opens vision of a means to shut off an accidentally to emit water, it may be easily shut off without opened sprinkler head, and comprises a pair of the use of valves, or having to go tothe main pivoted arms on one of which is located a curved valve, merely by raising the implement by its 5 element to fit a water vent and the other. arm handle l0, inserting the forward ends of the'arms is provided with a locating lug for engagement i4 and 34 through the ring-like support 50, and with the sprinkler head, there being a cam or the groove 42 acts as a guide for the usual pin 52 other means to force the arms apart to seat the which easily finds a seat in the depression 44, curved element on the water spout in the position opposite the button 20, which is then in position determined by the locating lug. directly over the spout 54. Upon pulling down Other objects and advantages of the invention on cord 56 the upper arm 34 is forced firmly will appear hereinafter. against the pin 52 and the button 20 is forced Reference is to be had to the accompanying down on the spout and closes it. The notch l8 drawing, in which allows the water stream to pass through the arm Fig. 1 is a side elevation of the device, with I4, thus obviating any deflection thereof, and 15 parts in section; said stream also acts as a guide, tending to center Fig. 2 is a. plan view of the device looking in the implement due to the undercut.
